CR-10 / Tronxy Mittens Cooler

<p>Let's keep it cool!</p> <p>My take on a better cooler for the CR-10 Tronxy X1/3 type hotend. The stock CR-10 set up can cool the heater block too much if you don't have it wrapped. The parts doesn't cool all sides well. My Tronxy X3 didn't have a parts cooler and the heater block couldn't get temps over 205C.</p> <p>I tried a couple other popular coolers but did not fit my original parts blower or just not that efficient.</p> <p>So the Mittens Cooler evolved. Printed in PETG, it weighs 12 grams. Has a bit fo a twist for a little vortex of air.</p> <p>Needs a few things: a 5015 blower/fan, a few screws, a bit of rewiring, and a bit of tenacity.</p> <p><strong>Reportedly <a href="/make:456819">works with the Tevo Tornado</a> now.</strong></p> <p><em>WARNING:</em> It works for me. Your results may vary wildly.</p> <p>I've gone through dozens and dozens of printed revisions to get to this version.</p> <p><em>If you find this useful and want to encourage my insanity, buy a <a href="https://www.paypal.me/idig3d/3">cup of coffee</a> for me, a <a href="https://www.paypal.me/idig3d/8">bag of coffee,</a> or you <a href="https://www.paypal.me/idig3d">pick the value</a>.

Send me one and I'll try to make one fit.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Creality CR-10</p> <p><strong>Rafts:</strong></p> <p>No</p> <p><strong>Supports:</strong></p> <p>No</p> <p><strong>Resolution:</strong></p> <p>0.2mm</p> <p><strong>Infill:</strong></p> <p>15%</p> <p><strong>Notes:</strong></p> <p>Printed with a 10mm brim.

If not, you may have a bit of over-extrusion.</p> <h3>Post-Printing</h3> <p><strong>Clean up</strong></p> <p>Break out the square support. Should snap out, but it it needs some coaxing, carefully use a hobby knife. Trim away the brim and any stray printed strands. Check the parts blower outlets and clean up as needed.</p> <p><em>WARNING: Use at your own risk. I've tested this best I can at this time and works great for me.
